Does anyone have ichyness....

Does anyone have ichyness for pregnancy symptom? Yesterday morning I noticed that my stomach around my incision scar is really itchy. It looks like I got bit but I haven't been naked long enough to get bit. Well after my shower, all of a sudden after I blow dried my hair my head has been itching like crazy. It's so bad that my head is now so sore. I tried coconut oil today and it helped but as soon as I washed it out I'm back to itching. I don't have lice or anything, believe me I checked. I don't know what to do. I can't stand it much longer. My scalp is torn up now. I don't know if it's an allergic reaction why all of a sudden now. I'm at a loss.
